[dpdk-dev] [PATCH] examples/vmdq: support i40e in vmdq example
This patch supports i40e in vmdq example.
1. queue index is added by vmdq queue base in rte_eth_rx_burst.
2. pool index is added by vmdq pool base when mac address is added to pools.
3. add some error message print
Besides, due to some limitation in PMD,
1. mac addresses are needed to be pre-allocated to VMDQ pools.
2. ports are started before mac allocation.
